Investors are cautious ahead of the Federal Reserve meeting, with the US dollar index holding steady and waiting for policy signals.

The US dollar's trend is stable, as investors are cautious ahead of the Federal Reserve policy meeting later this week. Jagdish Mamorial, an economist at Jefferies, stated in a report that Federal Reserve Chairman Powell may emphasize increased uncertainty in economic growth and inflation prospects. The tone may be not in a hurry to cut interest rates, but if necessary, the Federal Reserve will be prepared to respond.
